Hi Guys,
Somewhat new around here but not new to building bikes. Thought I would share a few pictures of a bike I have been building. I started with a 41 Schwinn DX frame and Tange TX1200 fork I picked up at a local swap meet. Initial plan was to just throw together a bomber with parts I had around the shop, so a single speed coaster brake bike, and just ride and enjoy. Well, after putting it together as a bomber I started looking around for the necessary parts to slowly change the bike into a shifter bike with gearing, effectively turning it into a hybrid as defined on Alan Bond's wonderful Clunkers web site.

Here is the first version of the bike built up as a coaster brake bomber. I used Worksman wheels as I had a set, then just some Wald cruiser bars, an Ashtabula crank and Schwinn stamped Ashtabula stem, and a Brooks B67 Saddle I had. Fun bike but limited with it's fixed single speed gearing.

From there I decided to locate all the "correct" parts as defined on Alan Bond's Clunker web site and change the bike into a true hybrid clunker. Some of the parts were hard to locate and some just kind of turned up at the perfect time. The wheels were converted to Atom hub Araya 7x beauties I stumbled into that were in really nice shape. The rear sprocket is a six speed Suntour. Both derailleurs are Suntour Cyclone. I then located a 175mm arm TA Specialities triple chain ring pedal crank. Derailleurs are operated with Suntour Mighty thumb shifters. Migura type brake levers to actuate the Atom drums. I messed with handlebars endlessly till I settled on a rare set of 24" Schwinn Scrambler bars that I widened from 26" to 32" and then added Hunt Wilde grips. Seatpost is solid bar stock aluminum that carries a proper vintage Brooks B72 with chrome rails. Finished the build off with some Schwinn style knobbie tires. Here is how it looks now.

Changing from a Bomber to a Hybrid really changed the whole personality of the bike. It is now a very usable machine. Sure, it's heavy compared to a modern mountain bike, but it can climb anything and just haul on the flat straights. I have been putting in the miles to learn this bike well, can shift any gear without looking and really am just enjoying my new hybrid clunker.

Thanks,
Pat

WOW, great job! Let me ask you this. What did you use to hold your cables in place? Safety wire?

Hi Talon,
Really like the build you did awhile back. Yeah, I have been using safety wire to hold cables on bikes for a long time. It's subtle and vintage. Plastic tie wraps look so out of place to me on a vintage build.

Really sweet. And they are such great riding bikes. Here's my 40:
Nicely done, Speed King. Yes they are great riding bikes. To all you guys sitting on the fence about building a klunker, the sooner you get started the better as the parts are getting harder to find. Once done you will quickly find you have a new favorite bike. Plenty of old school cool in a bicycle that can really be ridden hard.

I had used black string tie wrap on my build. But, I replaced it with leather strips with a pull over button. I agree with you, Zips seem out of place,

Thought I would post a couple pics from a recent visit to the Marin Bicycle Museum. They had a weekend swap meet that was pretty cool so me and a buddy took my 41 DX and my 81 Champion bikes up. Ran into Don Koski that used to own The Cove Bicycle Shop in Tiburon, California. Way cool guy. His shop was the main parts supply for the early MTB pioneers. He invited us and our bikes into the museum and asked if we could leave the bikes inside for the day, which we did. Also met Joe Breeze who was one of the main guys on the Mt. Tam crew. Lots of cool early MTB history in the Museum and some way cool people. Hope you guys find this interesting.
